Dog dies in overhead bin aboard United Airlines flight

However, the owner was reportedly forced by a flight attendant to put the dog carrier along with its occupant in the overhead compartment.

Another passenger, Maggie Gremminger, posted on Twitter that she heard the dog barking during the flight but assumed the overhead bins were ventilated.

"They assured the safety of the family's pet so wearily, the mother agreed", Lara wrote. It makes no mention of ever putting an animal in the overhead bin, which lacks proper air circulation for a living creature, according to The Points Guy.

The owner appeared distraught and heartbroken after discovering what happened to the dog at the end of the flight, she said.

Joined disclosed to ABC News it accepts full accountability for the dog's passing. "After the flight attendant asked her to move it above, the woman adamantly refused, communicating her dog was in the bag".

The French bulldog was traveling Monday with its owner and her children from Houston to NY.

"This was a tragic accident that should never have occurred, as pets should never be placed in the overhead bin", she stated.

"There was no sound as we landed and opened his kennel. I held her baby as the mother attempted to resuscitate their 10 month old puppy".

United Airlines said it was investigating the incident and expressed its condolences to the family.

According to the airline's website, pets are allowed on most flights within the U.S. In-cabin pets must travel in approved kennels that can fit completely under the seat, where the kennel must remain at all times.

However, the airline declined to comment on its official in-cabin pet stowage policy and whether the passengers have been compensated for their loss.
